FLUSHING-TANK.

-Spccification of Letters Patent.

Application filed August 2 2, 1916. Serial No. 116,350.

To all whom it may concern:

Be it known that we, Win00 BRIGHAM and Gnonen A. FunNnAUX, citizens of the United States, residing at Dufur, in the county of lVasco and State of Oregon, have inverite'd new and useful Improvements in Flushing Tanks, of which the following is a specification.

The invention relates to a flushing tank, and more particularly to the class of flushing tanks designed for flushing closets,fhoppers and bowls.

The primary object of the invention is the provision of a tank ofthis character wherein the fioatfor controlling the outlet of the tank is. of novel construction so that i the same will be positive in its operation and will dispense with the use of a plurality of valves, as but a single valve is employed therewith, which valve controls the inlet of the tank. I I

Another objectof the invention is the provision of a. tank of this character wherein the float is formed with a siphon tube which enables the contents of the tank to be siphoned when the float is actuated for the discharge of water from said tank.

A furtherobject of the invention is the provision of a tank of this characterwherein the construction thereof, is novel in form and the float therein for controlling the inlet and outlet of. the tank is readily and conveniently operated and will effect the automatic closing. of the valve controlling the inlet of the tank on movement of the float in one direction.

Astill further object of the invention is the provision of a tank of this character which'is extremely simple in construction, thoroughly reliable and efficient in its operation, strong, durable and ineXpe'nsive'in manufacturehand installation.

Other objects will be in part obvious and in part hereinafter set forthl I The invention accordingly consists in the features of"construction, combination of elements and arrangement of parts which will be exemplified in the construction hereinafter described, and the scope of the apsectional View thereof, showing the inlet valve in open position;

Fig. 3 is a view similar to Fig. 2, showing the inlet valve closed;

Fig. 1 is a bottom plan view of the float removed from the tank;

Fig. 5 is a top. plan view thereof.

Similar reference characters indicate corresponding parts throughout the several views of the drawings.

Referring to the drawings in detail, the flushing apparatus comprises a tank A of any approved construction. From the tank extends downwardly the flushing pipe B which leads to the bowl or other place to which the ,water is to'be supplied as usual, the upper end of said pipeB being projected within the tank A for a distance and is formed with a flared terminal 10 which forms the outlet mouth for the water contained within the tank.

Located within the tank is a buoyant float 11 which is formed with a bifurcation 12 pening through one end and with openings 13 providing guide passages through which project guide tubes 14 fastened to the bottom of the tank A and rise vertically therefrom so as to guide the float 11 in its vertical movement on the rise and'fall thereof, the bottom 15 of said tank A being dished and is formed concentrically or'about the flush pipe B with a well or recess 16 for a pur' pose presently described.

Leading into the tank is the inlet gooseneck end 17 of a water supply pipe 18 and at the point of the bight of the gooseneck 17 is formed a valve casing 19 in which is arranged a suitablewalve 20 for controlling the supply of water from the pipe 18 to the tank, the stem 21 of said valve being hori- Zonta'lly disposed and is protruded through a valve casing 19, while formed on this we ing is a hanger 22 to which is pivoted a lever 23 which has one end protruded into the path of the stem 21, while its opposite end is adjustably connected between adjust" ing nuts 24: on a stem 25 pivoted in bearings 26 'on' the float 11 so that on downward movement of the said floatthe lever 23 is actuated to relieve pressure upon the stem 21 and by the construction thereof the valve 20 automatically opens. When the float 11 rises it actuates the lever 23, moving its end into engagement with the valve stem 21 so as to operate the valve 20 for the closing thereof to shut ofl the water supply to the tank A while on the downward movement of said float the water is admitted to the tank, as is usual.

Formed in the float 11 and adapted to telescope over the flared terminal 10 and protruded portion of the flush pipe B within the tank A is a siphon tube 27 which is closed at its upper end and open at its lower end, the latter end being formed at opposite points with outwardly flared legs 28, and due to the fact that the diameter of the well is greater than the diameter of the lower end of the tube will, when the tube 27 is in lowered position, give a space between the legs and the inner circumference of the well 16. It will therefore be seen that the particular diameter of the tube and the provision of the legs, will permit all water to be drawn from the tank with the exception of a small quantity retained in the well, whereby in cold weather when the water is cut off from the main and the tank is flushed there is very little water left in the tank.

J ournaled in the side walls of the tank A at one end thereof is a rock shaft 29 to which are fixed arms 30 having pivoted thereto at their free ends links 31 which are also pivotally connected with the float 11. Bridging the arms 30 is a crank shaft 32 which is journaled for swinging movement in the tank A and has formed at one end thereof without the said tank an operating lever 33 carrying at its free end a suitable handle 34, and this crank shaft 32-is designed to act upon the arms 30 when the float 11 is raised within the tank A so as to depress the said arms and thereby lower the float 11 a slight degree for action upon the water contained within the tank A to force the same upwardly within the siphon tube 27 and thereby siphon the water from the tank A into the pipe B, and immediately upon relieving pressure upon the lever 33 the float ll-will again ride the surface ofthe water until the said water has been completely siphoned from the tank. The lowering of the water level carries the float downwardly into the tank A and the inlet valve is automatically opened for the refilling of the tank until said float 11 has reached a predetermined height within the tank A, whereupon the valve closes and shuts off the supply of water to the tank, as will be obvious. The bifurcation 12 in the float 11 forms a clearance for the gooseneck 17 of the supply pipe 18 within the tank.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the herein described flushing tank will be readily apparent and, therefore, a more extended explanation has been omitted.

Having thus described our invention, we claim:

1. A flush tank comprising a container, a flush pipe leading therefrom and having one end protruded therein, a float within the container and having a siphon tube telescoped over the protruded end of the flush pipe, a supply pipe leading into the container and having an inlet valve, a lever adjustably connected with the float and operative upon the valve for the opening thereof on the lowering of said float and the closing thereof on the rising of the same, a rock shaft journaled in the container and having arms connected with the float, a crank shaft pivoted in the container and bridging said arms, and an operating lever on the crank shaft and without the container.

2. A flush tank comprising a container, a flush pipe leading therefrom and having one end protruded therein, a float within the container and having a siphon tube telescoped over the protruded-end of the flush pipe, a supply pipe leading into the container and having an inlet valve, a lever adjustably' connected with the float and operative upon the valve for the opening thereof on the lowering of said float and the closing thereof on the rising of the same, a rock shaft journaled in the container and having arms connected with the float, a crank shaft pivoted in the container and bridging said arms, an operating lever on the crank shaft and without the container, and vertical guides within the container for the said float.

3. A flush tank comprising a container, a flush pipe leading therefrom and having one end protruded therein, a float within the container and having a siphon tube telescoped over the protruded end of the flush pipe, a supply pipe leading into the container and having an inlet valve, a lever adjustably connected with the float and operative upon the valve for the opening thereof on the lowering of said float and the closing thereof on the rising of the same, a rock shaft journaled in the container and having arms connected with the float, a crank shaft pivoted in the container and bridging said arms, an operating lever on the crank shaft and without the container, vertical guides within the container for the said float, the said container being formed with a well, and a bearing flange on the open end of the siphon tube to rest in the well on the lowering of the float.

In testimony whereof we affix our signatures.
